musicmusic, did you see this thread? I think it has great potential to use acoustic fingerprinting. Did you think through the possebility of an API for this?

What do you think about the possebility of storing an identifier to all clustered tracks specified by a certain threshold? That could help (at least me) creating playlists with duplicate tracks and sorting out in these. In addition something like "remove duplicates", but based on acoustic fingerprinting could be possible on playlists.
